The Great Pollet Sea Arch. This is a real hidden gem of Donegal – a spectacular natural sea arch and fantastic example of marine erosion. It is located on a totally unspoilt stretch of coastline and has a lovely pebble beach adjoining it. This beautiful landmark is much photographed and a quick internet search will bring up many fabulous images for you. It is a steep hike down to the beach from the road but you wont be disappointed! With very minimal signage, it is not the easiest place for the visitor to find – ask us for some detailed directions from our site.
